fetish to tall women

Since I know myself (even as a kid) i have been attracted to tall women, it is not like a normal prefferance people have, it is a fetish if i see a tall girl i get sexualy excited in anytime.
the taller the better if she is 6'9 it more attractive then 6'0...
i cant explain it and would really love to get some help with it, as i know it is a normal thing and it have a proffesional psychological reason. I even saw a quastion about that thing when i was doing an exam to join the militry... so if the militry find a reason to ask if i am attracted to tall woman in particular i guess that there is a reason. and i would like to know please.
i am 5'8 by the way.
thanks.
